Collect prototype material with its source.
Bring useful research pages, interface examples, screenshots, links, local files, and selected AI‑chat turns into one Book.
Collect web references with Picker ↓Your project library for AI prototypes.
Keep product references, user flows, interface ideas, source links, and review outcomes in one Book. Select only what the next AI prototype task needs.
How to prepare product material for an AI prototype task.
Choose context for one prototype task.
Use Connect with a selected Book, or Pack only the flow, constraints, references, and notes you want to take to another AI tool.
See agent collaboration ↓Save the outcome for the next iteration.
Record the review outcome, selected direction, and open questions you want to retain in the Book before choosing context for the next task.
What can you keep for an AI prototype project?
- Direction
What this prototype should test.
The task, user flow, constraints, interaction states, and selected references worth carrying into the prototype task.
- Sources
Research and references with their source.
Research pages, competitor examples, interface captures, local files, links, and notes about why a source is useful.
- Review
What to retain for the next iteration.
Review outcomes, selected direction, open questions, and agent results you choose to save as project records.
A comparison: scattered prototype files versus a prototype project Book.

Task context
Flows, constraints, and examples live across disconnected tools.
Keep the selected task context and supporting material in one Book.
Sources
Research and references lose their origin or why they were useful.
Keep selected source material and notes about why it matters together.
Review outcome
What was learned in an iteration disappears into another message.
Record the outcome, selected direction, and open questions you want to retain in the Book.
What reaches AI
Paste from memory or hand over a broad, unfocused project.
Select only the context for this prototype task and review suggestions before keeping them.
Collect from the web with Picker.
Picker is an optional browser extension. Save selected web text, images, links, or AI‑chat turns to the current Book while keeping the original source attached.

Work with AI in 2 ways.
Connect lets a compatible local agent work with the Book you choose.Pack prepares your selected materials and notes for any AI tool.
Connect a local agent.
Connect currently supports Codex and WorkBuddy. Agent suggestions return to your Book for review before you keep them.

Choose the sources, material, and notes for this task, then take them to your chosen AI tool yourself. A Pack never sends the whole Book automatically.

QwenQ&A
Does Sourcebook build the prototype?
No. Sourcebook keeps the sources, task context, and review outcomes you choose. Prototyping and testing stay in the tools you choose.
Do I need to give an AI the whole project?
No. Select only the material relevant to this prototype task. Pack never sends a whole Book automatically.
Is Picker required?
No. Picker is an optional browser extension for saving selected web material with its source.
Which agents does Connect support today?
Connect currently supports Codex and WorkBuddy. With other tools, Pack can still prepare the materials and notes you selected.
